rosr ne TRAY non Loose-LEAF nmnnns.

Application filetl August 5, 1927, Serial no. 210,893, and in GreatBritain February 24, 1927.

This invention has relation to improvements connected with posting traysfor loose leaf binders.

In mechanical or machine posting systems it is necessary to remove theleaves or sheets from the binder for placing in the typewriter or addingmachine and after the required entry has been made to replace them inthe binder. Mechanical or machine posting systems, therefore, requirethe employment of open back bindersor binders having detachablecovers,-one of the covers having locking mechanism integral therewithand the other or both of the covers having posts on which the leaves orsheets are placed.

The invention has for its obj ectto provide for the support of thecovers and leaves or sheets prior to and durinp, posting so that theyare held against displacement and for their replacement. I r

The leaves or sheets are preferably of the kind described and claimed inthe specilication of an application for Letters Patent filedsimultaneously herewith Serial No. 210,892. j a

In order that the invention, the 'objectand nature of which have beenset forth, may be clearly and readily understood, reference will now bemade to the constructional embodiment illustrated on the accompanyingdrawings, on which Fig. 1 is a perspective view;

Fig. 2 a side elevation with section;and i 1 Figs. 3 as sectional viewson the lines 3-I-l and l l respectively of liip,

11 is a base board on which towards one end two superposed plates 12 aremounted. The platcs12 are of d rent lengths, the upper being theshorter, and arcflanged: at each end. The plates 12 are so disposed thattheir flanged ends 13 are spaced apart. Between each pair offlanges 13,the end of an arm or side memberof a U-shaped frame 1 1 is pivotallymounted. 15, 15 are two blocks or inemb ers which are mounted on thebase board parallel to one another and so as to extend longitudinally''of the base board 11 a portion in from one end thereof. The blocks 15have} both ends sloping and on the sloping ends adjacent the end of thebase board 11 a plate 16 is mounted. This plate 16 is of such.

length that when mounted in position it extends behind and beyond thearms or slde members of the frame 1 1 to which 1t const1- tutes asupport. The portions of the plate 18 is secured.

=or recesses to the flange 18.

16which come directly behind the arms or side membersof the frame 1 1are cut away, as indicated at 17, to form recesses into which the armsor side members can extend. Betweenthe recesses 17 the plate 16 has onits forward edge an upstandingflange 18, which has at eachend anextension or lug 19. The recesses 17 are such that they support theframe 1 1 at a convenient angle to ensure easy ,manipulation of theleaves or sheets when posting is in progress. A pin 20, which extendsforwardly, is mounted on each or,

shown, on one of the lugs 19. The blocks 15, in addition to carrying theplate 16, constitnt'e carriers for a pair of members 21, each of whichconsists of a metal rod or bar, preferably of selnicylindrical section,bent as shown to somewhat more than a right angle. T l1enie1nbers21 arecarried at their one ends by brackets 22, to which they are securedandwinch are, 111 turn, mounted on the blocks 15 adjacent the ends to whichthe flzmged plate The members 21ers of such length and shape thatwhcntheir one ends are mounted described, tl'wll'flllllfll' ends comeabove and rest upon the otl'ier sloping ends of the blocks 15 inwhi'chpositions they are held by brackets 23. The members 21 are secured tothe brackets 22. and the brackets 22 are mounted on the blocks 15 insuch wise that the ends of the members 21 are spaced away from theflange 18, the ends "of the brackets22 coming directly below the flange18. The construction and arrangcment :i resuch that two depressions 2 1are formed directly adjack-int The brackets shaped at one part to engagethe members 21 and at another part are cut away, as shown at 25, to formrecesses or seats. 26 is a second U-shaped frame This frame 26is placedtowards the other end of the base board and is supported in an inclinedposition by brackets 27 mounted on the base board. The fra1ne26 is sopositioned that the free ends ofits arms 'or side members are in linewith the ends of the members 21 that "rest on the sloping ends theblocks 15. i As seen in sidevlew the fra1he26 with portions I The metal29 of the cover A contains the lock and this metal is provided with oneor two holes 28. The holes 28 are of a size and pitch to permit theengagement of the pin 6O i .It will be understood that double-post orpins therewith, and are further such posts 30,,- 31. The retaining post31, when posting'is in progress, is placed on a stand I orsupport-32mounted on the base board 11.

I lVhenfposting is to take place, the loose leaf binder is placed on thestand described with its cover A in eontactwith the frame 14 and itscover B resting on'the members 21 with the pin 20 (or pins) engaging thehole 28 (or holes)., The back edge of the cover A is positioned over,and may be partly entered into, the depressions or recesses 24, the backedge of the cover B resting on the members 21 preventing its completeengagement therewith. Displacement of the binderris-thus. prevented. Thelock is now-operated to release the cover B and permit vof its removalThe cover B when moved away from'the cover'A and leaves C is placed incontact with the frame 26 with its backedge bearing'on the members 21below' the brackets 23 and the posts 30 rest ing in therecesses25 ofsaid brackets. The

' 'brackets23 hold the posts in a; position in whichthe leaves can beplaced directly thereon when thus seated intherecesses 25, The cover Bis thus held againstdisplace- I ment. {As the cover with posts 30 iswith- 'drawn from cover A, the leaves 'move downwardly into engagementwith the members 21 and are held against lateral dis- ]plaeementby theengagement of the two projections. on the edge with the members 21.

as shown'in' Fig. When the cover B is w1thdrawn,the cover A is releasedand Wlll also move downwardly until it rests on the bottoms of therecesses orrdepressions 24. Y

The'retaining post 31 is nowremoved and placed in its holder; Postingcan now be undertaken, the leaves C being transferred one or moreat atimefrom the members 21 and placed on. the posts '30, any leaf on Vwhich it is desired to make an entry being placed in;thef"adding machineor typewriter duringits transfer. When all the leaves, C have beentransferred from the position adjacent cover Ato' thatadjacent cover B,the

retaining post 31 is passed through theholes.

34 in theleaves Ginto its seating in the 1 metal 33 of the cover B andthe cover A is transferred and locked to cover B.

: binders can be employed inwhich case the posts on one of the coverswill serve the same purpose as the members 21, the posts on each of thecovers being suitably supported to carry the leaves and to permit of thereconnection of the covers.

What I claim is 1. Means for dealing with the covers and leaves of aloose leaf binder of the post type during machine posting comprising abase board, oppositely inclined cover supports mounted on the baseboard, angled leaf supports also mounted on the base board and disposedbetween the cover supports, and

brackets to support the posts on one of the covers mounted adjacent oneof the cover supports.

2. Means for dealing with the covers and leaves of a loose leaf binderof the post type during machine posting comprising a base board,oppositely inclined cover supports mounted on the base board, angledleaf supportsalso mounted on the base board and disposed between thecover supports, a plate mounted behind one of the cover supports andcarrying means to engage the cover resting thereagainst to prevent itslateral displacement and brackets to support the posts on the other ofthe covers mounted adjacent the other of the cover supports.

3. Means for dealing with the covers and leaves of a loose leaf binderof the post type during machine posting comprising a base board,oppositely inclined cover supports each consisting of a U-shaped framemounted on the base board, the one fixedly and the other pivotally,angled leaf supports also mounted on the base board and disposed betweenthe cover supports, a

flanged plate mounted behind the pivotally mounted cover support tosupport the same in its operative position, a pin mounted on said plateto engage a hole in the one of the covers and brackets to support theposts on the other of the covers mounted adjacent the fixed coversupport.

4. Means for dealing with the covers and leaves of a loose leaf binderof the post type during machine posting comprising a base board,oppositely inclined cover supports mounted on the base board, angledleaf supportsalso mounted on the base board and disposed between thecover supports, a plate mounted behind one of the cover supports vandcarrying means to engage the cover resting thereagainst to prevent itslateral displacement and brackets constituting a means of attachment ofthe angled leaf supports and a support for the posts on the other of thecovers mounted adjacent the other of the coversupports.

Dated this 22nd day of July, 1927.
